Why did the air traffic control outage cause so much havoc?

It caused a deduction in the UK’s air traffic control system Chaos at the UK and beyond airports Wednesday.

The error lasted only 20 minutes, but it was enough to place a planes throughout the country and caused 150 flight cancellation and delays until Thursday.

So, what’s wrong with this vital air traffic technology?

NATS, which is partly owned by the government, manages the entire airspace in the UK for flights from the country’s airports.

Wednesday’s problem, Swanwick’deki National Air Traffic Control Center, which is understood to have problems with the radar imaging system, “a problem with a problem”, he said.

Nats said the problem was “quickly solved by switching to the backup system”.

However, he said the problem was different from the problems he faced in August 2023. At that time, more than 700,000 passengers were affected when 500 flights were canceled due to a large deduction.

Nats, during the deduction on Wednesday, the traffic reduces the safety reasons and there is no “no evidence” that any cyber attack was caused, he added.

Transportation Secretary Heidi Alexander told him that NATS was “an isolated event and that there is no evidence of malignant activity.”

NATS is working on an internal investigation into what happened, but there will be no official report to the Ministry of Transport.

In order to understand how such a short radar failure can cause so much destruction, Graham Lake, former director of Civil Air Navigation Services (CanSO), said that people should imagine NATS air traffic network as “national infrastructure”.

“Think of the network as highways in the sky,” BBC said.

“For any reason, when you lose something like the scope of the surveillance radar, your network’s ability falls into a country lane.

“That’s why the systems slow down when there is a technical failure.”

Airlines became vocal in NATS criticism, and said that its system failed for the second time since 2023.

Airline, Ryanir, NATS General Manager Martin Rolfe’nin asked to resign and the previous failure “no lesson” learned.

Easyjet said, “Again, it is a great disappointment to see the great failure that disappoints many customers with long delays in our Air Traffic Control System and in some cases.”

Passengers are asked to check their flight information, some said that they were temporarily trapped abroad due to the disruption.

Mr. Lake, BBC’s program today, technical failures “inevitable” and “healing rapid” arguing that the call of the loss of work of Mr. Rolfe’nin does not believe that the call was fair, he said.

Even with the problems in 2023, Nats performs well “If you look at the interruption minutes for a year,” he said.

However, Air Traffic Control Consultant Doug Maclean added that it is “nonsense” to admit that errors are inevitable, and that the radars “are not covered three times, but almost everywhere in the country”.

He continued: “Will you endure this with your bank? Would you accept them by saying that your salary has been sent to someone else?”

Mr. Maclean also questioned the lack of detailed explanation about what Nats is.

“A monopoly in a national service will be allowed to have such failure and to be transparent about what failure is?”

Mr. Lake said that NATS performed well in comparison with other countries that suffered from air traffic problems and said that Wednesday’s issue is a bad chance.

“The UK airspace is definitely very busy among the most intense of the world. We are in the most intense time of the year and yesterday failure was at the busiest hour of the day, so it is not ideal.”

The Heathrow Airlines Operators Committee, representing the Airlines flying from the airport as a result of the blockage in the sky of England, called more tracks to increase capacity in the south -east of England.

“NATS operational teams are doing an extraordinary job,” said Nigel Wicking, the general manager of the group, but the system “Working hot” and “things went wrong and the system is great when we lose an hour.”

British government said that Heathrow supports the expansion of Gatwick and Luton airportsHowever, critics argue that plans will increase emissions and air pollution.
